Federal Boulevard De-Channelization and Trail Project

Federal Boulevard De-Channelization and Trail Project

The project proposes a SITE DEVELOPMENT PERMIT for the de-channelization (concrete-removal) of 1,885 linear feet (LF) of Chollas Creek, construction of 3,100 LF trail, and native landscaping around the trail and banks of the creek, on a site containing Environmentally Sensitive Lands (ESL). The proposed project would remove 2.26 acres of impermeable concrete channel, widen the channel, and construct 2.84 acres of channel lined with natural stone and native vegetation. A new retaining wall of varying heights (7 to 12 feet) would be installed along the southern side of the creek and the slope would be replanted. An existing bridge and reinforced concrete box (RCB) currently used to access a sewer manhole on the south side of the creek would be removed, and the sewer manhole would be removed and replaced with pipe. Concrete encasement would be installed along 65 LF of sewer Vitrified Clay Pipe (VCP), and a 60 LF 8” VCP would be relocated. Four stone drop structures and one concrete spillway and stone energy dissipator would be installed for grade stability in the creek. Five access ramps on the north side of the creek would be used for maintenance and stabilized with armor-flex (or equivalent) and native herbaceous vegetation. Proposed staging would occur on the northwest and east ends of the project area. After creek improvements occur, the northwest staging area would be revegetated with native shrubs and trees. A 3,100 LF asphalt trail with widths varying 5-12 feet would connect existing sidewalks to the west and east of the project. The project site is east of Interstate (I) 15 and Home Avenue, north of State Route (SR) 94, west of Sunshine Berardini Field, and south of Federal Boulevard in the City of San Diego. The project is not located within or adjacent to the Multi-Habitat Planning Area (MHPA). The project is located on right of way owned by the City of San Diego and California Department of Transportation (Caltrans) and requires a Caltrans Encroachment Permit. The project is located in the RM-1-1, RS-1-1 and RS-1-7 zone within City Heights in the Mid-City Communities Community Plan Area in Council District 9.
